Black membrane digester and red mud digester are both common biogas fermentation equipment, which play an important role in biomass energy utilization and organic waste treatment.
Here are their pros and cons and how they work:
Low cost: Relatively inexpensive, suitable for small-scale producers or households.
Easy to install: Simple installation and easy maintenance.
Good heat preservation effect: The black film can absorb sunlight and is conducive to maintaining the temperature of the biogas fermentation process.
Wide applicability: It is suitable for treating all kinds of organic waste, such as household kitchen waste.
Shorter lifespan: The service life of the digester may be shorter than that of other types of digesters.
Poor stability: Due to the thinner material, it may not be as stable as other types of digesters.
The black film biogas digester uses the principle of biological fermentation to put organic waste (such as agricultural waste, kitchen waste, etc.) into the biogas digester and produce biogas through the action of microorganisms. The black film of the black film digester absorbs sunlight and increases the temperature inside the digester, which is conducive to the growth of microorganisms and the fermentation process.
Strong stability: Relatively stable, suitable for long-term operation.
Wide applicability: It is effective in dealing with different types of organic waste.
High gas production efficiency: Enables more efficient biogas production.
The cost is higher: Compared with simple biogas digesters such as black film biogas digesters, red mud biogas digesters have higher construction and maintenance costs.
Complex installation: Relatively complex, requiring professional design and construction.
The red mud biogas digester produces biogas by adding organic waste to a closed container and using the fermentation gas production process of microorganisms. Red mud digesters are usually designed with different areas, including fermentation areas, biogas collection areas, etc., to promote the production and collection of biogas by controlling conditions such as temperature and stirring.
